Well the last few series have had a weird sister thing going on.
Who knows? Maybe that'll become Kamen Rider's new thing, instead of bikes, it's long lost siblings.
Here is a theory about the pairing that will appear:
WataruxMegumi(Who didn't see that one coming)
YurixJiro(How do you think Megumi came to be)
OyotaxQueen Fangire(see Kiva's origin theory)
NagoxHis own reflection(Why doesn't he die already)
And here is a theory about the current IXA system: Everytime the user destroys a Fangire, a small fragment of the Fangire's soul is absorbed into the IXA system. Meaning after every Fangire killed, the user of the IXA system will become more vampire-like and eventually transform into a Fangire.
